VENTILATION oF HATS.

Specification forming part of Letters PatentNo. 26,692, dated January 3, fliSQRessueld Marchi i which- Figure l, represents the under part of a hat with my improvement attached `to it. Fig. 2, represents a section through a portion ofthe rim, body, sweat-cloth, and ventilator, and Figs. 3 and 4, represent the ventilating piece detached from the hat. y

I am aware that Ventilating holes have been made in the sweat-cloth of a hat. These holes get closed up to the air while they allow the perspiration to pass through them and stain or soil the exterior of the hat. I am also aware that corrugated metal pieces have been introduced between the lining and the exterior of the hat, to `make these Ventilating openings. of course impervious to the perspiration, and it will preserve `its air spaces, but it is an exceeding uncomfortable thing to p ress against the head, and thus fails to come into use. v

My obj ect is to make a hat thatwillventilate while on the head of the wearer, that will not allow the perspiration to pass through it, that will not close up by the pressure in wearing it, and that willgive a smooth bearing surface for the head. And

all these elements I find in the ventilating` strip which I shall hereaftermention, ap-

plied between the sweat cloth andthe ex-` terior of the hat.

To enable others skilled in the art to make and use my invention, I will proceed to describe the same with .v reference to the drawings.

I take a crescent shaped piece of prepared rubber, gutta-percha, which will `extend around the forepart of ahat, as seen at Fig. 3, marked A, one side of which a is made The metal is v into corrugations, Iandkthelothergfside` plain and smooth.` This pieceA,""s putint the hat between the sweatigclothc and :the` body d of the hatf--thesmoothgsideflamentI the head, and the corrugated side a nextftli` hat body, and thus thereis a smoothbearing for the forehead against thewentilatin piece, and the openings through it nextgth brim,\cannot, owing to thefnatlurefof th material out of whichfuthe `Ventil;iting` `piec A is made close up. veryggood way@ making these `Ventilating istrips is tollirs mold the piece as shownat Figu4j, lanf af terward divide it asshown the red in therein, and thus make twooutofqitl'lhi makes the holes of Fig; `14,-, intogrooveso corrugations as sl1ow1ratFig-f3., the piece Fig. 4, may beusedentire, fthongh is heavier than necessary. d Il much prefer j` y however the plan; shown at .]:"`ig.`` 3,a`s Y C itis much lighter and makes as good: alvel y lation. i, Q f
